Gramps

"Do you really wish to know?"Spoilers from the books and/or games to follow!

Gramps is an old cannibal who lives in the island hut in the north-east part of the swamp. Geralt first meets him near the landing. When he asks if Gramps has any witcher's work, he is offered the opportunity to escort the old man to Melitele's Shrine. Geralt points out that he was hoping for paid work, but takes the job anyway. (There is the option to tell Gramps to "piss off".)

He is especially partial to elf meat, but finds dwarf meat, at least he thinks it was a dwarf he fought a drowner for, too stringy. He also has some standards: he never eats children. I guess that is some comfort.

If you kill him, depending on the timing, the lumberjacks may turn on you. On his body you will find Wives' Tears, amber, and 30 .

Sometimes he will bug out when you enter the cave in the swamp. He can be found again near the ferryman, but he will not follow you anymore, even after speaking to him, reloading the game, and triggering cutscenes with him. You can still complete the quest by shoving him to the Shrine. He will, however, still flee from monsters. But he will still not follow you.

Gramps may be a reference to The Picture in the House, a short story by H.P. Lovecraft. In Lovecraft's story, there is also an old, cannibalistic man living in an remote, dilapidated hut.
